Public holidays to avoid
Dates where one side is off work while the other is not are the most common cause of no-shows on this route.
- Monday, October 12, 2026 — Indigenous Peoples' Day — San Francisco is off, Mumbai is working.
- Wednesday, November 11, 2026 — Veterans Day — San Francisco is off, Mumbai is working.
- Thursday, November 26, 2026 — Thanksgiving Day — San Francisco is off, Mumbai is working.
- Friday, December 25, 2026 — Christmas Day — San Francisco is off, Mumbai is working.
Mumbai and San Francisco have no shared working hours, so a recurring live meeting always costs someone their morning or their evening. Rotating the burden, or moving the update to written form, is usually the better answer.
Sending a booking link avoids the arithmetic entirely: each side picks a time in their own zone and both calendars get the correct local time, including after a daylight-saving change. See how LemCall handles cross-timezone bookings.
